Application filed March 3, 1916. Serial No. 81,785.

To all whom it may concern Be it known that 1, WILLIAM H. WOOD, a citizen of the United States, residing at .South Euclid, in the county of Cuyahoga and State. of Ohio, have invented a certain new and useful Improvement, in Lamps, of

which the following is a full, clear, and exact description, re erence being had to the accompanying drawings.

This invention relates to lamps and more particularly to the reflectors which are employed with lamps such as are used on motor vehicles. The invention, broadly considered, consists'in a reflector which is so constructed as to direct and diffuse rays of light in such manneras will utilize the reflected rays for the purpose of illuminating a particular section of the ground or roadway but will render v such illumination largely, ifnotsubstantially, free from contrasting lights and shadows thus rendering the illumination more uniform in character and more nearly approximating the illumination due todaylight than has been accomplished by devices of this kind heretofore in use. A further object of the invention is to provide a two-part reflector, one.

party at least of said reflector being of the parabolic type whereby rays of light impinging thereupon will be reflected in parallel lines, While the other opposed partof the reflector is arranged with its axis angularly disposed with respect to *the first part or' reflecting surface whereby one of the parts or members of the reflectorwill. direct at 'least's'ome of the rays of light reflected thereby to a different portion of the ground or roadbed than that illuminated; by the other part or member. More limitedly stated, the invention contemplates the provision of a two-part reflector wherein the upper part is a parabolic reflectoroperating in the usual manner while the other art comprises a I parabolic reflector which is adapted and arranged to reflect at least some of the rays of light. impinging thereagainst forwardly and downwardly and ontodifierent parts of the roadbed or ground than are illuminated by the first mentioned reflector. Further and more specifically stated the invention comprises a pair of opposed parabolic reflecting surfaces the axes whereof are arranged at an angle to'each other; also a pair of opposedparabolic reflecting surfaces which are relatively adjustable.

addition to the pair of opposed parabolic reflecting surfaces, my invention comprises the employment, with a parabolic reflecting surfacesuch as the upper portlon of an ordinary parabolic reflector of an opposed reflecting member having certam specific features of construction whereby efl'ective illumination may be secured, the

reflecting surfaces serving to diffuse the rays tical section taken through a standard re- 1 flector shown-in the manner in which my attachment and the lamp are appliedand positioned; Fig. 4 a horizontal sectional view taken through the central portion of the reflector, the attachment being shown in plan; and'Figs. 5 and 7 diagrammatic views, similar to Figs. 1 and 4, respectively, showing the manner in which the various reflecting surfaces of the attachment cooper-' ate with the reflector; and Fig. 6 a diagrammatic view of the front of the attachment showing the manner in which the lateral wings cooperate with a source of light to direct the rays to predetermined parts of the ground or roadway at eachside of the vehicle. a

Describing by reference characters the various parts illustrated herein, 1 denotes an ordinary parabolic reflector having at the rear central portion thereof a neck 2 which is adapted to receive the socket 3 of a lamp 4, the source of light whereof is indicated at 5. The parts thus far described are of 0rdi nary or standard construction.

In practice, only the upper half or portion of the parabolic reflector will be used as the lower part is cut out by the cooperating reflectpr member which, in the exemplification"""o'f. my invention embodied herein, isv

"an a'ttachment comprising a plurality of parabolic reflecting surfaces which are spaced along the direction of the axis'of the reflector and which surfaces are connected by a series of reflecting surfaces, each series comprising a plurality of flat or plane re fleeting faces so united as to form a broken curved surface, each broken curved surface thus formed having its region of concentration in advance of the source of light. Each curved series of flat reflecting faces is connected with the adjacent series by means of a step which is arranged at such an angle as not to reflect any of the rays of light from the source. ln addition to the reflecting surfaces describechthe attachment is provided with lateral wings arranged to intercept certain of the rays from the lamp and to reflect them downwardly and laterally for the purpose of illuminating the roadway or ground in the vicinity of the wheels of the automobile and laterally therebeyond. ln addition to these wing reflectors, the attachment has a small concave reflector projecting upwardly the base of the lamp bulb which serves to direct the rays downwardly.

A denotes the attachment generally cornprising a reflecting body and suitable positioning springs, which will be described hereinafter. The reflecting body is preferably a single sheet of metal and comprises a rear parabolic reflecting surface 6 having an aperture 7 near the upper end thereof which is adapted to receive the socket 3 of the lamp. Above this aperture, there is located the small concave reflector 8 referred to hereinbefore. The attachment is generally semicircular in transverse section and flares or is enlarged outwardly and forwardly from its rear end. At its base, the reflecting surface 6 unites with the first broken curved reflecting surface B, which comprises a plurality of flat reflecting faces 9. The reflecting surface B is set backward from the source of light and is so inclined that no rays of light will be reflected rearwardly of the source of light 5, but these rays-indicated diagrammatically at bwill strike the upper surface of the reflector l at such an angle as will cause them to be directed forwardly and below the horizontal. The action of each .flat face of the reflecting surface B will be referred to hereinafter.

The reflecting surface B is connected with the next reflecting surface C in advance thereof by means of a step 10, this step being preferably arranged so that a plane embracing the same will extend forward of the source of light whereby no reflection will occur from this surface. As will appear from the diagrammatic view in Fig. 5, rays of light from the source reflected forwarlly of the and will strilre the up er ha l flector i in such manner as to 1 flected f dly downwa cated at 0.

by a step 11 to the surface C, such step being arranged similarly to the step 10, whereby no reflection will occur therefrom. it will be observed that the surface C is set in wardly or in advance of the surface D and that the surface D is set inwardly or in advance of the surface E, the purpose being to prevent reflecting any light from the sur faces B G and l) outside the upper part of the reflector 1.

Referring again to Fig. 5, it will be seen that rays of light (Z from the source of light 5 impinging upon the surface D will be reflected to the upper part of the reflector 1 and there will in turn be reflected in the direction indicated by the lines (Z' that is to say. downwardly and forwardly.

The end of reflecting attachment is flarech as indicated at ll, providing a forward parabolic reflector. This reflector and the parabolic reflector 6 reflect rays from the source of light downwardly and "i"( rwai'dl y will appear from Fig. 5, wherein a ray of light 6 from the source of light 5, impinging upon the reflector 6, is directed forwardly and downwardly along the line 6 while three rays of light 6 from the source o light 5 impinging upon the surface E are flected parallel to each other, as indicated 7 the rays 8 Because of the fact that the flector G is a parabolic reflector all of the a s of light will be reflected parallel to each otheras indicated at 6 and will illumii: ate the part of the roadway beyond the rays of light reflected by the parabolic surface E. The broken curved surfaces and the parabolic surfaces of the attachment extend on opposite sides of the axis of the reflector 1 and substantially to the same horizontal plane with said axis. The metal is then bent outwardly to form a front shoulder 12 and a rear shoulder 13 on each side of the axis in substantially the same plane therewith, whereby these shoulders will not serve as reflecting surfaces for the light. From the outer edge of each of these shoulders there projects a reflecting flange 1e and respectively. These flanges proiect inwardly from bottom to top whereby they prevent the rays from the source of light from strik ing the parabolic reflector l at the sides therebehind thereby eliminating the useless and objectionable side rays that are ordinarily thrown such reflectors; in addition to serving this function the flanges 14 and 15 provide reflecting surfaces which direct the rays of light in the manner shown 6 and 7 5 is to say, they direct t forwardly downwardly,

.iese views rays of light v flector 1.

of the surfaces 14 and 15 will be directed not only forwardly and laterally, but that these rays, though diffused, are directed upon the points which it is desired to illuminate, without impinging upon the reflector 1.

In practice, the reflecting surfaces, 14 and 15 efl'ectively illuminate the curb, the Wheels and the ground adjacent to and extending laterally therefrom-the term ground being used generically. They are particularly valuable in illuminating crossroads, streets, or alleys at either side of and in advance of the vehicle. It will be noted further that the wings 14 and 15 are set at an angle to each other and are spaced back. This peculiar construction enables them to operate for the purpose described but without interfering with the reflection of rays from that portion of the reflector 1 thereabove which it is desired to utilize.

The surface 8, being parabolic, reflects any rays of light that may impinge thereupon in a direction parallel to each other and, because of its inclination, in a direction slightly below the horizontal.

Attention has been called heretofore to the fact that each of the reflecting surfaces 13, C and D comprises a plurality of flat faces indicated at 9, 17 and 18, these flat faces being set at an angle to each other, whereby each series of such flat surfaces constitutes a broken curved surface. The purpose of using these flat faces is to greatly diffuse the arays of light which impinge thereupon and are reflected therefrom to the upper surface of the reflector 1. greater the width of each of these flat faces, the greater will be the dilfusion of light rays therefrom to the parabolic reflector 1 thereabove. The width shown in the drawings has been found to be extremely eflicient in that it secures a difl'usion which is, however, sufficiently concentrated as to its limits to secure, with the angular relation of the surfaces .B, C and D, a lighting effect which approximates that obtained by daylight. This effeet is enhanced by the provision of the parabolic surfaces 6, 8 and E, which serve to reflect forwardly and downwardly-but to difl'erent areas of the roadway-the rays of light which impinge thereagainst from the source 5. Furthermore, the angular relation of the surfaces B, C and D to the source of light and to the reflector 1 is such that no rays from these surfaces'escape without reflection from the upper part of the re- Furthermore, these rays are not only all reflected by the upper part of the reflector 1, but they are so reflected that the illuminated zone is confined to a position below .the horizontal, thus preventing any interference with the vision of pedestrians and drivers of other'vehicles'.

In order to obtain the best results from The the use of my attachment, it is necessary that it should be properly positioned with reference to the source of light and to the reflector. More specifically, this attachment should be-so placed and positioned that the '70 two parabolic surfaces 6 and E shall reflect the rays to different parts of the ground than those illuminated by the reflector 1 and then be anchored in place. To permit of conveniently positioning the attachment in this manner, I prefer to use a pair of flat springs, one of which, G, is secured to the back of the attachmentpreferably below the neck 16 thereof through which the lamp socket extends. This flat spring G has a pair of substantially horizontal arms. 9 whichare adapted to-yieldingly engage the back of the reflector 1. In addition to the spring G, a downwardly and forwardly extending spring H is secured to the back of the attachment, conveniently by the same rivet G by which the spring G is secured thereto. This spring H is provided with a slot in which is adapted to receive an anchoring post 19 having its lower end bent, as indicated at 20, whereby it may be inserted through a hole 21 in the reflector 1 and be hooked behind said reflector, the. upper end of the post projecting through a hole in the reflecting surface E and being threaded and provided with a nut 22.

With this construction, the-operator inserts the post 19 in place through the lower wall of the reflector 1, places the socket of the bulb within the neck 16, and pushes the attachment back in place against the yielding resistance of the springs G and H. When the lamp socket is properly positioned and secured with reference to the lamp and the attachment is also in proper functioning 16-5 relation to the main reflector, it is anchored by setting up on the nut 22, against the yielding resistance of the springs G and H. When it is desired to remove the reflector, it is necessary only to disconnect the bulb 11-11 socket and to remove the nut 22, the springs tending to move the attachment outwardly as the nut is slackened.

- The construction just described provides a particularly efiicient means whereby one of the reflecting members may be set and anchored in such position as will secure the most effective illumination, and especially whereby one of two parabolic reflecting surfaces may be set with its axis at the desired angle to the axis of the other; also simple and effective means whereby the adjustment of such members may be secured if desired, although such change will ordinarily be unnecessary after the members have once been set in their desired relative positions.

While I have necessarily shown and described my invention in detail, 1t W111 be obvious that these details may be departed from more or less and that various altera- .130

tions may be made as to th exact construction and relative arrangement of the various reflecting surfaces. 1 therefore do not propose to limit myself to such details except as the same may be positively included in the claims hereto annexed or as such limitation may be rendered necessary by the state of the prior art. lhus, so far as the angular relation of the parabolic reflecting surfaces is concerned, my construction might be embodied in a two-part reflector comprising an upper half-parabolic reflector and a lower half-parabolic reflector.
